Abstract

Approximately 1.1 billion people currently live in countries where consanguineous marriages are customary, and among them one in every three marriages is between cousins. Opinions diverge between those warning of the possible health risks to offspring and others who highlight the social benefits of consanguineous marriages. A consanguinity study group of international experts and counselors met at the Geneva International Consanguinity Workshop from May 3, 2010, to May 7, 2010, to discuss the known and presumptive risks and benefits of close kin marriages and to identify important future areas for research on consanguinity. The group highlighted the importance of evidence-based counseling recommendations for consanguineous marriages and of undertaking both genomic and social research in defining the various influences and outcomes of consanguinity. Technological advances in rapid high-throughput genome sequencing and for the identification of copy number variants by comparative genomic hybridization offer a significant opportunity to identify genotype-phenotype correlations focusing on autozygosity, the hallmark of consanguinity. The ongoing strong preferential culture of close kin marriages in many societies, and among migrant communities in Western countries, merits an equivalently detailed assessment of the social and genetic benefits of consanguinity in future studies.

  • If consanguineous marriages tend to occur in families with a tradition of close-kin unions, using F from recent pedigrees will bias results.

    “This will bias the results if, as seems plausible, consanguineous marriages tend to occur in families with a tradition of close-kin unions (Hussain and Bittles 2000; Hamamy et al. 2011).”

  • This prediction agrees well with the estimated 3.5-4.4% increased risk for prereproductive mortality and 1.7-2.8% increased incidence of congenital anomalies in children of first cousins above the general population risk.

    “This prediction agrees well with the estimated 3.5 -4.4% increased risk for prereproductive mortality and 1.7 -2.8% increased incidence of congenital anomalies in children of first cousins above the general population risk (Hamamy et al. 2011).”

  • Over the past centuries, consanguineous marriages were a common practice, and the custom remains prevalent in many countries.

    “Over the past centuries, consanguineous marriages were a common practice, and the custom remains prevalent in many countries (Bittles and Black 2010a; Hamamy et al. 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
